Question 68

A company's Security Engineer has been tasked with restricting a contractor's IAM account access to the company's Amazon EC2 console without providing access to any other AWS services. The contractor's IAM account must not be able to gain access to any other AWS service, even if the IAM account is assigned additional permissions based on IAM group membership.

What should the Security Engineer do to meet these requirements?

Options:

A.

Create an Inline IAM user policy that allows for Amazon EC2 access for the contractor's IAM user.

B.

Create an IAM permissions boundary policy that allows Amazon EC2 access. Associate the contractor's IAM account with the IAM permissions boundary policy.

C.

Create an IAM group with an attached policy that allows for Amazon EC2 access. Associate the contractor's IAM account with the IAM group.

D.

Create an IAM role that allows for EC2 and explicitly denies all other services. Instruct the contractor to always assume this role.

Question 69

A company is hosting a static website on Amazon S3 The company has configured an Amazon CloudFront distribution to serve the website contents The company has associated an IAM WAF web ACL with the CloudFront distribution. The web ACL ensures that requests originate from the United States to address compliance restrictions.

THE company is worried that the S3 URL might still be accessible directly and that requests can bypass the CloudFront distribution

Which combination of steps should the company take to remove direct access to the S3 URL? (Select TWO. )

Options:

A.

Select "Restrict Bucket Access" in the origin settings of the CloudFront distribution

B.

Create an origin access identity (OAI) for the S3 origin

C.

Update the S3 bucket policy to allow s3 GetObject with a condition that the IAM Referer key matches the secret value Deny all other requests

D.

Configure the S3 bucket poky so that only the origin access identity (OAI) has read permission for objects in the bucket

E.

Add an origin custom header that has the name Referer to the CloudFront distribution Give the header a secret value.

Question 70

A security engineer receives an IAM abuse email message. According to the message, an Amazon EC2 instance that is running in the security engineer's IAM account is sending phishing email messages.

The EC2 instance is part of an application that is deployed in production. The application runs on many EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group across multiple subnets and multiple Availability Zones.

The instances normally communicate only over the HTTP. HTTPS, and MySQL protocols. Upon investigation, the security engineer discovers that email messages are being sent over port 587. All other traffic is normal.

The security engineer must create a solution that contains the compromised EC2 instance, preserves forensic evidence for analysis, and minimizes application downtime. Which combination of steps must the security engineer take to meet these requirements? (Select THREE.)

Options:

A.

Add an outbound rule to the security group that is attached to the compromised EC2 instance to deny traffic to 0.0.0.0/0 and port 587.

B.

Add an outbound rule to the network ACL for the subnet that contains the compromised EC2 instance to deny traffic to 0.0.0.0/0 and port 587.

C.

Gather volatile memory from the compromised EC2 instance. Suspend the compromised EC2 instance from the Auto Scaling group. Then take a snapshot of the compromised EC2 instance. v

D.

Take a snapshot of the compromised EC2 instance. Suspend the compromised EC2 instance from the Auto Scaling group. Then gather volatile memory from the compromised EC2 instance.

E.

Move the compromised EC2 instance to an isolated subnet that has a network ACL that has no inbound rules or outbound rules.

F.

Replace the existing security group that is attached to the compromised EC2 instance with a new security group that has no inbound rules or outbound rules.

Question 71

A company’s public Application Load Balancer (ALB) recently experienced a DDoS attack. To mitigate this issue. the company deployed Amazon CloudFront in front of the ALB so that users would not directly access the Amazon EC2 instances behind the ALB.

The company discovers that some traffic is still coming directly into the ALB and is still being handled by the EC2 instances.

Which combination of steps should the company take to ensure that the EC2 instances will receive traffic only from CloudFront? (Choose two.)

Options:

A.

Configure CloudFront to add a cache key policy to allow a custom HTTP header that CloudFront sends to the ALB.

B.

Configure CloudFront to add a custom: HTTP header to requests that CloudFront sends to the ALB.

C.

Configure the ALB to forward only requests that contain the custom HTTP header.

D.

Configure the ALB and CloudFront to use the X-Forwarded-For header to check client IP addresses.

E.

Configure the ALB and CloudFront to use the same X.509 certificate that is generated by AWS Certificate Manager (ACM).
